Billions of people live in cities but how many of us actually live in our city? Hugo Macdonald, author of the book How to Live in the City, takes us to New York, Tokyo and London with tips noting down how to thrive in these urban hubs using pens from Cross's new city-inspired Peerless 125 Special-Edition Collection, inspired by iconic works of architecture; London's Elizabeth Tower, New York's Chrysler Building, and Tokyo's Skytree Tower.
